  • For the dual gear train driving structure at input side of basin-type gear of the present invention, the differential gear set input rocker arm driven by the basin-type bevel gear in the differential gear set assembly is made to be driven by two sets of transmissions, in which the first transmission transmits the rotary kinetic energy between the differential gear set input rocker arm and the engine, the second transmission transmits the rotary kinetic energy between the differential gear set input rocker arm and the second driving unit, and one or both of the transmissions drives the differential gear set input rocker arm.
    • (b) Description of the Prior Art
  • Traditionally, for the hybrid drive system, in which the basin-type bevel gear of the differential gear set assembly drives the differential gear set, the drive bevel gear at the input side of the differential gear set usually couples with the basin-type bevel gear to form the first transmission, to transmit the power from the engine, and the bevel gear driven by the second driving unit, such as the electric machinery, couples with the same basin-type bevel gear to transmit the kinetic energy between itself and the electric machinery, and the shortcomings are that the basin-type bevel gear driven by the kinetic energy of the electric machinery of the second driving unit and the engine is transmitted by the input bevel gear, thus the speed ratio is limited to be the same with that of the input side of the engine, and the bevel gear must be the same with another coupled input bevel gear driven by the rotary kinetic energy of the engine.
